Provisioning Timeout

When using the MWTM provisioning feature to modify the management interface, sometimes the operation fails with this message:

No prompt response

This response can occur when changing the duplex or speed attributes for the Ethernet interface. The response can also occur for other interface attributes that affect IP connectivity between the MWTM and the device.

The default setting for a provisioning operation timeout is 50 seconds. As a workaround, the system administrator can increase the TGS_OP_TIMEOUT attribute in the System.properties file to a higher value. You must restart the MWTM server for this change to take effect.

SSH-Enabled Nodes

The MWTM Node > Home Page right-click menu option does not work correctly for the following SSH-enabled IP Transfer Point (ITP) nodes:

•Cisco 2600

•Cisco 7200

•Cisco 7300

•Cisco 7500

•Cisco 7600

The browser launches, as expected, but the user is not prompted for login information.

Note This limitation exists for any ITP node running the 12.2(x) IOS with SSH enabled.

INSTANCE_NUMBER on Single-Instance ITP

Symptom If a command with INSTANCE_NUMBER is included in the UserCommands.ts file, the instance number will appear on all nodes in the GUI. If you run this command on a node that does not have multi-instance enabled, it fails.

Workaround If you have a network with both single-instance and multi-instance nodes, you must configure a separate set of troubleshooting commands for each node type in the UserCommands.ts file. Do this by grouping the commands for each type under a separate category.

Multiprocessor Multithread Vendor Exception

Sometimes when using the MWTM client on a Solaris multi-processor computer, an exception occurs when the topology window is open and you are manipulating views. The workaround is to close the topology window, then reopen it.

External SSH Client Use

If you enable the MWTM terminal proxy (mwtm termproxy) and use an external SSH terminal client to connect to a device, you might receive a warning message indicating a man-in-the-middle attack. This warning occurs because the MWTM server is operating as an SSH proxy to the device. In this scenario, ignore any warning messages indicating a man-in-the-middle attack. These warnings do not occur if you disable the MWTM terminal proxy or if you use the SSH terminal included with the MWTM.

SSH and Telnet Terminal

The SSH and Telnet terminals that are included with the MWTM provide basic terminal functionality. They do not support non-English character sets or the UNIX curses library (for example, colors). If these, or other, additional terminal functions are required, you can configure the MWTM to use an external SSH or Telnet program.

Tooltip Text Truncated

The Firefox 2 browser truncates tool tips that contain long text strings (see Firefox bug 218223). The MWTM contains only a few tool tips that exhibit this problem. The problem is resolved in Firefox 3. The problem does not occur when using the Internet Explorer (IE) browser.

Credentials for Nodes with Multiple IP Address

Credentials for a node are associated with a unique IP address. If a node has more than one accessible IP address, functions that require credentials might not resolve to a credential based on the selected IP address, and the requested function would fail. The MWTM functions that require credentials include:

To work around this limitation, specify the credentials for all accessible IP addresses for a node.

Unprintable Characters

CSCse81393

In various GUI and web pages, simple text fields might contain unprintable characters. An example is the Model Name PID field for a RAN service (RAN_SVC) card in an ONS chassis. This is a cosmetic problem and does not affect functionality.

Symbol Style and Line Style Preferences

CSCsg83861

The preferences dialog box of the MWTM client interface allows you to customize the way that data series appear in charts. You can specify series color, line style, and symbol style. However, symbol style and line style preferences do not work when displaying real-time charts for MSU rates and for RAN backhauls and shorthauls.

Java Exception

CSCsh15638

The following exceptionwith corresponding stacktrace can occur. The MWTM captures this exception in the sgmConsoleLog.txt file:

java.net.SocketException: Broken pipe

This exception can occur when users access the MWTM web interface and frequently abort connections while the server is under heavy load (for example, during discovery). Clicking the Stop button on the web browser or navigating to a different web page before the current page finishes loading can cause this exception to occur.

Note The root cause of this condition is an internal bug in the Tomcat web application that ships with this release of the MWTM.

You can safely ignore these log messages.

Avoid Colon (:) in ITP Object Names

CSCsh58070

The following error messages may appear when performing these operations:

Operation

Error Message

Generating link report by using the sgmLinkStats.sh script

sgmgawk: cmd. line:45: (FILENAME=- FNR=???)
fatal: division by zero

Attempting to import link and linkset report data

ERROR 38000: The exception
'java.sql.SQLException: Invalid character
string format for type SMALLINT.' was thrown
while evaluating an expression.

Using the ITP route table deployment function

Invalid Linkset in Route Table: [???]

These error messages occur when ITP linkset, AS, and ASP names contain a colon (:). To prevent these errors, do not use the colon (:) in ITP linkset, AS, and ASP names.

Note In general, the MWTM does not support ITP AS, ASP, or linkset names that contain special characters, such as: !@#$%^&*()+=[]{};',./\:"<>?|

Unprintable Characters in GUI

On some GUI windows and web pages simple text fields might contain unprintable characters. An example is the Model Name PID field for a RAN service (RAN_SVC) card in an ONS chassis. This might occur one some RAN_SVC cards in an ONS chassis.

Appearance of MSU Rates Real-Time Charts

The preferences dialog box of the MWTM client interface allows you to customize the way that data series appear in charts. You can specify series color, line style, and symbol style. However, symbol style and line style preferences do not work when displaying real-time charts for MSU rates and for RAN backhauls and shorthauls.

Provisioning Problem Due to Credentials

After switching the SNMP IP address, provisioning stops working due to credentials. Credentials for a node are associated with a unique IP address. If a node has more than one accessible IP address, functions that require credentials might not resolve to a credential based on the selected IP address, and the requested function would fail. The MWTM functions that require credentials include:

•Discovery of ONS and RAN_SVC nodes

•Troubleshooting

•Provisioning

•Route and Global Title Translation (GTT) table deployment

This might occur with nodes with multiple, accessible IP addresses with credentials set for a subset of those IP addresses. To work around this limitation, specify credentials for all accessible IP addresses for a node.

Special Characters in ITP AS/ASP/Linkset Names in Reports

The following error messages might appear when performing these operations:

Operation

Error Message

Generating link report by using the sgmLinkStats.sh script

sgmgawk: cmd. line:45: (FILENAME=- FNR=???)
fatal: division by zero

Attempting to import link and linkset report data

ERROR 38000: The exception
'java.sql.SQLException: Invalid character
string format for type SMALLINT.' was thrown
while evaluating an expression.

Using the ITP route table deployment function

Invalid Linkset in Route Table: [???]

The error messages occur when ITP linkset, AS, and ASP names contain a colon (:). To work around this problem, remove the colon (:) from ITP linkset, AS, and ASP names.

Using MWTM With the RealPlayer Plugin Installed

If you use a computer that has the RealPlayer plugin installed, the Provision launch window will not work properly. When you change types on the Provision launch window, the provisioned item list will not refresh.

This is a known issue with the RealPlayer plugin. This issue occurs on both Internet Explorer and Firefox browsers.

Disable the RealPlayer plugin to use the Provision launch window. If you use Internet Explorer, you might need to reboot your computer after disabling the plugin. If you use Firefox, you might need to restart your browser after disabling the plugin.

Online Help System

The online help system is updated only during major release updates. New features added in patch releases (for example, 6.0.4) are not contained in the online help system. Instead, new features are documented in the release notes for the patch release.

APN and GTP Reports Disabled for GGSN on Patch Upgrade

CSCtj21269

If you enable GGSN reporting in MWTM 6.1.1 and then upgrade to MWTM 6.1.2 and apply the latest service pack, then APN reports are disabled. You may have to re-enable the APN reports even if they were previously enabled.

Historical Statistics Collection During Upgrade

When you upgrade to MWTM 6.1.6 from an earlier version, there may be a temporary stop in the collection of data. This could result in a time gap shown in historical reports for shorter interval reports (For example, 15 minute reports). No intervention is required for collection to resume.

Important Notes

This section contains important notes about RAN Backhaul Utilization.

RAN Backhaul Utilization

When the backhaul utilization for transmit traffic exceeds 100%, the likely cause is oversubscription of the shorthaul links that constitute the backhaul. The backhaul utilization is the amount of traffic that the system attempted to send, not the amount that was actually sent. If utilization is greater than 100%, you should see queue drops or other errors during the same time period. A backhaul utilization of greater than 100% is possible for a heavily loaded link with some occasional oversubscription.

New Features and Resolved MWTM Caveats

The following new features and bugs fixes have been fixed in MWTM 6.1.6:

The user specified an IP address that does not exist for the specified card slot.

Configuring M3UA or SUA offload, or Local Peer offload

Error: XXX is already
offloaded to this
linecard slot=xx

The user specified a target card slot that is already in use by another M3UA or SUA offload, or Local Peer offload.

Note The ITP does not allow mixed types between M3UA or SUA offload, and Local Peer offload.

Configuring the line priority for the clock source line option on the Cisco 2600 T1/E1 controller

% Invalid input detected
at '^' marker.

The '^' marker points to the line priority: primary or secondary.

While configuring the clock source line priority option on the T1/E1 controller, the user specified the primary or secondary option on the line, but the WAN Interface Card (WIC) card has only one port, and does not support the line priority option.

Configuring the secondary line priority for the clock source line option on the Cisco 7xxx ITP T1/E1 controller

% Invalid input detected
at '^' marker.

The '^' marker points to the secondary line priority: primary or secondary.

When configuring the clock source secondary line priority option on the T1/E1 controller, the user specified a number that is greater than the supported range on the device. Although the MWTM allows values 1-72, some cards only support 1-8 or 1-16.

Workaround None. The user must know the ITP card information and specify correct values in the provisioning request.

•CSCsz16365

Symptom When provisioning IPRAN nodes from the Provision tab of the web interface, some provisioning operations might fail on the node with these symptoms and conditions:

When a Sonet CEM Group is created on SPA-1XCHOC12/DS0 and SPA-1XCHSTM1/OC3. The SPA's are primarily used to configure Sonet Serial interfaces, but user creates Sonet CEM Group in MWTM provision request.

Changing framing on Sonet Interface

controller SONET <x> framing sdh

invalid input
detected at '^'
marker

When changing framing on the Sonet interface from 'sonet' to 'sdh' option on SPA-1XCHOC12/DS0 SPA. This SPA is primarily used only in the STS mode but user is changing to the AU-4 mode in MWTM provision request.

Provisioning speed for Gigabit Ethernet interfaces

interface GigabitEthernet<x> speed nonegotiate

invalid input
detected at '^'
marker

When configuring the speed as 'nonnegotiate' on Gigabit Ethernet interfaces. This speed option applies only for DS3 interfaces but user is configuring on non-DS3 Gigabit Ethernet interfaces in MWTM provision request.

Provisioning cablelength option for T1 controllers

controller T1 <x> cablelength short <x>

invalid input
detected at '^'
marker

When configuring cablelength 'short' on SPA-8XCHT1/E1. SPA-8XCHT1/E1 is used mainly for MLPPP bachhaul, but user is configuring the cablelength options of SPA-24CHT1-CE-ATM used for shorthaul PWE3 xconnects in MWTM provision request.

Provisioning ATM Interface for a controller, "mode atm aim <x>"

Might succeed but no ATM interface is created on the device

When configuring more than allowed ATM interfaces on 1941 and 3800 device types. The count of ATM's depend on the AIM card used like AIM8 or AIM4 card, but user is creating more than allowed ATM's in MWTM provision request.

Workaround None. The user must know the card/slot/module type information and submit provision requests based on the capabilities of the card.

•CSCsz56999

Symptom When provisioning IPRAN nodes from the Provision tab of the web interface, some provisioning operations might fail on the node with these symptoms and conditions:

Provisioning Action

Symptom

Condition

Creating 76xx Serial interface "channel-group <x> timeslots <x>"

invalid input detected

When serial interface is created on SPA-24CHT1-CE-ATM SPA. This SPA is primarily used to configure Circuit Emulation Functions [CESoP and SAToP], but user creates channelized serial interfaces in MWTM provision request.

Provisioning ATM Framing for 76xx ATM interfaces "atm framing <x>"

Invalid input detected

ATM Framing option can be provisioned only on SPA-2XOC3-ATM or SPA-4XOC3-ATM SPA, but user sets ATM Framing option on SPA-24CHT1-CE-ATM in MWTM provision request.

Enabling PTP for 2941 Vlan interfaces "ptp enable" option

Error: local interface

sure to turn it on

When configuring PTP, the GigabitEthernet interface port associated with the Vlan is not up and user selects this Vlan to enable PTP.

Configuring speed for 2941 Gigabit Ethernet interfaces "speed <x>"

invalid input detected
at '^' marker

When configuring speed option for GigabitEthernet ports 0 and 1 and these ports do not support the speed CLI.

When configuring more than two Serial controller channels per WIC on 1941 or more than four Serials per port on 2941 devices.

Workaround None. The user must know the card type information and submit provision requests based on the capabilities of the card.

•CSCsu02993

Symptom When IOS running-config contains the following characters in the object name, MWTM web user interface may exhibit unexpected behavior:

Double quote (")

Less than (<)

Conditions When IOS running-config contains following characters in the object name:

Double quote (")

Less than (<)

Additional MWTM provisioning or other functions may behave unexpectedly when IOS running-config contains following characters:

!,#,$,%,^,*,(,),',+,=, and ,

Workaround Remove special characters from IOS running-config.

•CSCtf51338

Symptom The MWTM web client is very slow or unresponsive when expanding the Default View node in the inventory tree.

Conditions Internet Explorer version 6 is being used as the web browser. The network latency between the web client and the MWTM server is very high. MWTM is being used to monitor a medium-sized or large network.

Workaround Use a different web browser such as Firefox or Internet Explorer 7 or later.

•CSCtf56323

Symptom When provisioning IPRAN interfaces with a VRF from the Provision tab of the web interface, provisioning operation might fail with "Incompatible with xconnect command on <x> - command rejected." Similarly while provisioning a PWE3 Xconnect on IPRAN object, the provisioning operation might fail with "Incompatible with ip vrf command on <x> - command rejected."

Conditions Both PWE3 Xconnect and VRF appear to be mutually exclusive on Parent-Child interfaces. On some interfaces, if Parent has PWE3 Xconnect then child interface of the parent cannot add VRF and vice versa.

Workaround None. The user must gain knowledge about the parent-child interfaces and specify correct values in the provisioning request.

•CSCtf54835

Symptom When provisioning IPRAN Gigabit or Ten Gigabit Ethernet interfaces with a VRF from the Provision tab of the web interface, the provisioning operation might fail with "% Invalid input detected at '^' marker."

Conditions Gigabit and Ten Gigabit Ethernet interfaces can be provisioned either with switchport or VRF. When the Ethernet interface is already set as switchport, the user is attempting to configure VRF in the MWTM provision request.

Workaround None. The user must have knowledge about the interfaces and specify correct values in the provisioning request.
